Email Agent Mcp

List recent emails with filtering by unread status, folder, sender, and limit. Use offset for pagination. A row with `isDraft: true` is an unsent draft — it has NOT been sent, and its `receivedAt` is provider-supplied metadata, not evidence of delivery. Never describe such a row as a sent, delivered, or received email.

Read the full content of an email by ID, transformed to token-efficient markdown. When the response has `isDraft: true` the message is an unsent draft — it has NOT been sent, and `receivedAt` is provider-supplied metadata, not evidence of delivery; never describe it as a sent, delivered, or received email. Set format to 'html' to get the raw body HTML instead of markdown — use this when you need to preserve inline styling (colour, background-colour, underline, strikethrough) that the markdown conversion discards, e.g. to change one sentence of a formatted body and leave the rest alone. Raw HTML costs far more tokens than markdown, so leave the default alone unless you need the styling; check `bodyFormat` (`text` means the message had no HTML part, so do not send it as HTML) before writing a body back, and never write one back with `bodyTruncated: true` — you do not have the whole body. strip_quoted_history and strip_signatures are markdown-shaped text transforms and are NOT applied when format is 'html'; the HTML is returned verbatim. To write it back, call create_draft/update_draft with format: 'html' AND force_black: false — force_black defaults to true and wraps your HTML in a force-black div, so leaving it on nests another wrapper on every round trip. Set strip_quoted_history to true to drop the terminal "On … wrote:" / Outlook-header / `>`-prefix reply chain and replace it with a short marker. Set strip_signatures to true to remove detected signatures and legal disclaimers; it defaults to false here for MCP compatibility even though the core action defaults to true.

Search emails using full-text query across one or all mailboxes. Use offset for pagination. Results include unsent drafts: a row with `isDraft: true` has NOT been sent — its `receivedAt` is provider-supplied metadata, not evidence of delivery. Never describe such a row as a sent, delivered, or received email.

Get mailbox connection status, unread count, and warnings

List every configured mailbox: its logical `name` (pass this as the `mailbox` argument to other tools), its `emailAddress`, provider, connection status, and which one is the default. Reports mailboxes that failed to authenticate too, so it stays useful for diagnosing a broken setup.

Retrieve all messages in a conversation thread by message ID. A thread can end with an unsent draft reply: a message with `isDraft: true` has NOT been sent, so it is not a sent reply — though earlier sent replies from the same author may exist elsewhere in the thread. Never describe such a message as a sent, delivered, or received email.

Compose and send a new email. Gated by send allowlist. Draft mode bypasses allowlist. If a send fails with SEND_STATUS_UNKNOWN, the message may already have been delivered; do not resend without checking Sent Items.

Reply to an email within an existing thread. Default reply_all=true cc's the original thread; pass reply_all=false to reply only to the sender. Send path validates all effective recipients against the send allowlist; draft path bypasses. If a send fails with SEND_STATUS_UNKNOWN, the message may already have been delivered; do not resend without checking Sent Items.

Create an email draft. Supports body_file with YAML frontmatter. Use reply_to for threaded reply drafts, where to and subject are derived from the parent message and may be omitted; pass reply_all=false with reply_to to draft a sender-only reply.

Send a previously created draft. Enforces send allowlist before sending. Rate-limited. If a send fails with SEND_STATUS_UNKNOWN, the message may already have been delivered; do not resend without checking Sent Items.

Update a draft email. Body edits are refused for reply drafts; non-reply body edits require replace_body=true and replace the body wholesale. Subject, recipients, and attachments remain editable. Allowlist is enforced at send_draft time, not here.

Cancel a pending provider-held scheduled send. Only verified scheduled drafts can be cancelled.

List pending provider-held scheduled sends for a mailbox

List attachments for a specific email message

Download a single attachment as inline base64. Default max_size_mb=5 (hard ceiling 25). File attachments only — Microsoft item/reference attachments return NOT_SUPPORTED.

Apply labels or categories to one or more emails

Flag or unflag an email as important/starred

Mark an email as read or unread

Delete an email (disabled by default, requires explicit configuration)

Move an email to a specific folder (inbox, archive, trash, etc.). Returns the new message ID since Graph assigns a new ID after moving.

Recursively list mail folders, including computed paths for nested folders

Create a custom child mail folder (defaults to a child of Inbox)

Delete a custom mail folder, including any mail it contains (disabled by default, requires explicit configuration). Well-known/system folders are protected.

List server-side inbox rules with all fields reported by the provider

Create a persistent server-side inbox rule using safe actions only; forwarding, redirection, and deletion are blocked. Confirm with the user before calling — this creates a rule that keeps acting on the mailbox 24/7 after the session ends.

Delete a server-side inbox rule by id (disabled by default, requires explicit configuration). Removing a rule can silently re-expose the mailbox to mail the rule was filtering.
